chapter 6

Which of the following is the primary purpose of a cooling system in an automotive engine?

• To improve fuel efficiency

• To increase engine power output

• To prevent engine overheating

• To reduce exhaust emissions

The cooling system in an automotive engine typically circulates which of the following fluids?

• Brake fluid

• Transmission fluid

• Coolant/antifreeze

• Engine oil

The component responsible for transferring heat from the engine to the coolant in a cooling system is called the:

• Radiator

• Water pump

• Thermostat

• Fan clutch

The purpose of a thermostat valve in a cooling system is to:

• Control the flow of coolant to the radiator

• Regulate the engine oil temperature

• Activate the electric cooling fan

• Prevent coolant freezing in cold weather

Which of the following cooling system components is driven by a belt connected to the engine crankshaft?

• Radiator

• Water pump

• Thermostat

• Heater core

The primary function of a radiator fan is to:

• Cool the engine oil

• Control coolant flow

• Increase engine power output

• Enhance airflow through the radiator

Which of the following statements is true about a water-cooled engine compared to an air-cooled engine?

• Water-cooled engines are generally more fuel-efficient

• Air-cooled engines require more frequent maintenance

• Water-cooled engines are better suited for high-performance applications

• Air-cooled engines are more resistant to overheating

The cooling system of an automotive engine should be flushed and refilled with fresh coolant at regular intervals to:

• Prevent rust and corrosion

• Increase engine horsepower

• Reduce engine oil contamination

• Extend the life of the radiator fan

What is one potential cause of coolant leakage in an automotive cooling system?

• Overheated radiator

• Clogged water pump

• Faulty thermostat

• Loose hose connections

Which of the following is a common symptom of a malfunctioning cooling system in an automotive engine?

• Decreased fuel efficiency

• Increased engine power output

• Engine overheating

• Reduced exhaust emissions
